IMPROVED SNOW-PLOW FOR RAH-WAYS.

The Schedule referred to in these Letters Patent and making part of thesame.

To whom it may concern:

Be it known that I, GHARLESL. GARFIELD, of the city and county ofAlbany, and State of New York, have invented a new anduseful Improvementin Snow- Plows; and I hereby declare the following to he a full andexactdescription of the same, reference bcinghad to the accompanyingdrawings, and to the letters of reference marked thereon,making a partof this specification, the sameletters always referring to the same partof the machine.

My said improvement has for its object the removal of snow fromrailroad-tracks, and from other roads, to

prevent the same. from becoming an impediment to' travel; and

It consists, mainly, in the combinationlof means by which the snow iselevated above thetrack or bed of and thence, gradually inclining upwardto the height to which it is deemed necessary to raise the snow beforeejecting the same to one side. This inclined plane is likewise combinedwith ahorizontal plane, and with a horizontal wheel, tnrbinated in form,having .broad blades revolving around an axis parallel with the'lines ofthe rail or track of the road, so as to receive the snow while the sameis in motion, in respect to the machine, upon the blades of the wheel,and cast it on one side, over the snow at the side of the road.

In the'accompanying drawings- Figure l is a representation of theseveral parts of the plow, combined together for united action. It isthere represented as enclosed in an outer case, so asv to extend-thecase over the trucks, wheels, 850., be-

7 yond the rails ortrack of the road, for the purpose of protecting themachinery and trncks'fr'om the impedi 'ment of the snow. Thecombinatio-nincludes, among other things, the inclined plane a a, the horizontalplane b, the turbinated wheel 0 c c, the guide or director d d, thefront lateral wings a e, the truck-wheels w w w w, and the means bywhich'they are connected for united action.

Figure 3 is a partial representation .of the front part of the casing orfront lateral wings K, with the inclined plane a a partially foldedback, to show the position of the shaft or axle s s, and the 'wheelswho, placed there for the purpose ofsupporting the lower extremity ofthe incline plane, the wheels 11: 10 Testing and turning upon the railor track. V

Figure 4 is arepresentation of so much of the improvement as shows themode of operating the turbinated wheel 0 c c, by means of thetruck-wheels r -r and connecting-axle, and the pulley-wheels p and pwith the connecting-cords; a

Figure 2 represents the guide or director (1 (I, used in combinationwith the inclined and hon'zontal planes, andthe turbinated wheel, forthe purpose: of guiding the snow to the one or the other side of theseplanes in its ascent to the wheel, according-to the side of the roadupon which it-is desirable to deposit the same.

Figure 5 is afront view of that part of the improvement represented byfig. 3, together with its encasiug accompaniment, and it is drawn torepresent the mode of applying such casing to fig. 3, the process ofsuch application being represented by fig. 5.

Figure 6 is a representation substantially of fig. 1, with the frontwings ce in said figure removed, and the director omitted.

Figure 7 is a. similar view, having-the triangular sides suppm'tingtheincline plane, substituted for the front wings, and the front andupper'portions of the sides of the casing It It removed.

Figure 8 is a representation similar to fig. 1, with position of theincline plane folded back, to show the the plow when used for lightsnows.

Figure 9 is a representation of the front wings e e, folded back, andthe incline plane cc folded up, ready for using the ordinary plow forlight snows h h, with its extension-wings i r The turbinated wheel,intbe accompanying drawings, is represented as revolving on a horizontalaxis.

It may be advisable to construct some machines with.

such wheel revolving on a vertical axis, where the machine is to be usedfor great depth of snow. Either method of revolving the wheel willanswer as an cle- Iiient of my said improvement.

This improvement is constructed upon the principle that the snow uponthe track or road-bed to be removed, -n1ust,'in, general, be lifted orraised up, byv means of the inclined plane, so as to be in position tobe ejected on one side of the track, into, over, and upon the adjoiningsnow, by means of the turbinated wheel, which is made to revolve ineither direction, according as desired. The incline plane ,is soconstructed as to reach a horizontal plane a few inches before meetingthe wheel, for the purpose of bringing the snow and blades of the wheelinto contact before the-snow falls upon the surface of the horizontalplane,

' and comes to a state of restin respect thereto; be-

cause, while the snow is relatively in motion, and before coming incontact with the surface of the horizontal plane, it will require muchless power to cast it aside than after coming into such contact; for, if

the snow fall upon, or be found in contact withthe surface of a plane,adhesion at once takes place be- .the drawings,I have used pulleys andcord.

operation of the machinery.

tween it and the plane, which will add, to the resistance to removal, anamount equal to such resistance multiplied by the velocity of theblades.

In the construction of machines for the removal of snow, it becomesimportant at all times to avoid, as much as possible, friction betweenthe surfaces of the 7 machine and the snow; for this reason, the changeof the incline to a horizontal plane, just before reaching theejecting-wheel, becomes a very important improvement.

In operating the incline plane for raising the snow above the track orbed, the pressure of the snow upon the incline plane, when running withthe necessary speed, will be great, making it necessary to support theplane by means of wheel and axle, as represented ments for reversing themotion of the turbinated wheel,

when desired, are well-known mechanical devices, deemed unnecessary tobe represented.

For the purpose of protecting the machinery used in revolving thewheel,.the casing 0 0 0 o, 856., fig. 5,. is prepared, into which themachine, represented in fig. 4, is adjusted, as shown in fig. 5.\Vithout such casing, the snow and'iee might adhere to the wheels,pulleys, cords, '& c'., and interfere with the successful machine,including wheels, trucks, 860., from impediment, the outer casing, asshown in fig. 1, is used:

When the snow is not deep, the ordinary plow, or one as represented infig. 7, may be used. In fig. 7 the trout end of the axle of the wheel 0c c is supported by the triangulated guide-post y.

In passing through deep snow or drifts, where tun-. nelling isdesirable, the arrangement of fig. 1 may be To protect the entirewheelmay be elongated, and be made to revolve vertically instead ofhorizontally.

Having thus fully described my said improvement and invention, I willproceed to set forth what I claim as my invention, and what I desire tosecure by Letters Patent.

I do not claim, broadly, the uselof an inclined plane for raising thesnow above the bed or track, to be cast aside, over and off the side 'ofthe track; nor do I claim the combination of the inclined plane with theguide or director (I (I, made adjustable to either side of the track;nor do I claim, broadly, the wheel 0 c c, for ejecting the snow over theside of the road or track; but

' What I claim as my invention, is-

lflhe combination of 'the incline plane a a, the

horizontal plane b, the guide or director (Z d, and the .wheel 0 c c,for united action, substantially as described.

2. The supporting-wheels w w, and connecting-axle s s, at the front ofthe incline plane .a a, in combination with such incline plane,horizontal plane b, director d d, and wheel 0 c e, for united action.

and Wheel 0 c c, substantially as desciibed 4. The case 0 o o o, incombination with the turbinated wheel 0 b c, and the truck, pulley,wheels 1' r,

5. The outer casing vk c, in combination with the incline. plane, thehorizontal plane, the director, and the wheel 0 c c, for united action,as described.
